To all 'whom it may concern:

Be it known that I, THADDEUS GALVIN, a citizen of the United States of America, residing at Detroit, in the county of Vayne and State of Michigan, have invented certain new and useful Improvements in Valves, of which the following 1s a specification, reference being had therein to t-he accompanying drawings.

The invention relates to a valve capable of being applied to the discharge opening or openings of the ordinary city, iydrant to which the fire hose is connected, the object being to provide an independent shut-olf for each discharge port whereby a number of ports may be coupled to without the necessity of operating the main valve controlling the supp y of water to the hydrant.

The invention consists in the novel construction of the valve, in its peculiar forma tion whereby it may be mounted within the discharge opening of the hydrant, in the arrangement and combination of parts, and in various details of construction as will be more fully hereinafter set forth.

In the drawings,-Figure 1 is a vertical central section through my improved valve, showing its application to the hydrant; Fig. 2 is an elevation of the valve casing; Fig. 3 is a vertical central section through the valve proper and its operating mechanism; Fig. 4 is a view similar to Fig. 2 of the part of the valve mechanism carrying the means of attachment to the hose; and Fig. 5 is a detached view in elevation of the packing retainer.

In the drawings thus briefly described, A designates the barrel of a hydrant of ordinary construction, and B the discharge port' or opening therein, there bemg usually anumber of these openings or hose connections for each hydrant. The discharge opening as shown in Fig. l is provided with an internal screw-thread a to engage a corresponding thread hereinafter described upon the valve mechanism.

C represents the valve casing, which is of tubular form, of a length to be msertcd within the discharge opening and to project within the barrel a considerable distance, and provided with an external thread b to engage the hydrant thread, and an annular section c forming a wrench-hold whereby the casing may be screwed within the hydrant in the manner indicated.

The casing terminates at its outer end at the wrench-hold, and this end of the casing is open so as to permit of the free discharge of the water. The rear end D is closed as indicated, while two openings E F are formed in the wall of the easing near its rear end, constituting inlet ports for the water supply from the hydrant barrel.

G represents a central tubular section of greater length than the casing, and arranged eoncentrically therein. It carries at its outer end beyond the casing a collar H, constituting an abutment for the valve operating member, as will be hereinafter explained, and a threaded section I beyond the collar constituting the means of attachment for the ordinary hose. At its inner end it is preferably rigidly connected to the end D of the casing by suitable screws, as J. The member described is provided with ports L M that are adapted to register when the parts are connected with the ports E F of the casing, as shown in Fig. 1.

O designates the controlling valve for the inlet port, in the form of a shell interposed between the member G and the casing, and adapted to slide longitudinally in the latter to close and open respectively the inlet ports.

P designates an operating member for the valve of tubular construction, internally screw-threaded as at Q to engage an external thread It upon the valve, and having at its outer end a suitable wrench-hold formed thereon, in this instance in the form of complementary pins or studs S.

The valve O is provided with a hw Z adapted to travel in a groove e formec in the member Gr, whereby as the valve is shifted longitudinally within the casing relative rotary movement will be prevented.

The member P has formed in its outer end an annular' recess f that receives, as indicated in Fig. l when the parts are assembled, the collar II of the member Gr, a portion g of the operating device extending below the collar, as indicated in Fig. l, so as to be held by said collar against outward n'iovement.

To prevent leakage, a packing is provided for the valve to seat upon, a similar packing is interposed between the valve and its cas ing, and a third packing between the valve and the central stem section G.

The letter K designates the packing against which the valve seats, which for the urpose of being properly held in place is interposed between the central? section G and the inner casing end, and is held by the screws J which pass through the packing as shown. The seat-portion of the packing extends` as indicated between the section G and the valve casing, and longitudinally of the casing to a point in proximity to the casing port, Vthe proportion of 'the parts being such'v that the valve in closing will passslightly beyond the port before it seats. The packing. between the valve land its casing, designated by thereference-letter T, is arranged in an annular recess T formed `in they interior ofy the casing, as. plainly shown in Fig. 1. The' casing is also counterbored, as at T2, and a ringl T3 is screwed therein to abut against the packing, the ringy preventing the packing from being displaced by the valve. l

U represents the packing interposed between the valve and the central tubular section G, and is preferably located in a recess 0, formed in the central section. l

In assemblingY the valve partsthe member G' is inserted within thev valve', and. these two parts subsequently positioned within the valve casing, the member G being' then connected to the casing by the screws described. VVhen thus assembled, the valve `is screwed within the discharge opening of the hydrant in the'manner indicated, the casing projecting a sulhcient distance within the hydrant barrel to permit of the free discharge off the water through the inlet ports of thev valve mechanism. The flow of water from the discharge opening is controlled by the shell` or gate valve by rotation only of the operating member l?, and the hoseengaging section I is held in a fixed position to receive the hose.

What I claimV as my invention is,-

l.v In a valve mechanism, the combination with an lelongated tubular valve casing having` its ends respectively open and closed, and an inlet formed in the cylindrical wall near the closed end', of a tubular member concentrically arranged within the casing and connected to the closed end of the latter, a shell valve interposed between the tubular member and casing and slidable longitudinally of the latter, a cup-shaped packing positioned within the closed end of they casing serving as a seat for the valve andY held to the casing by the' concentrieally arranged member, and meansfor operating the valve.

Q. In aV valve mechanism, the combination with a tubular valve casing provided' with an inlet near one end thereof, ofv a shell valve slidable longitiidinallyvwithin the casing and controlling its inlet,l an annular packing between the valve and casing, a rotatabletubular' operating member for the ceases valve extending within the casing in proximity to the packing, and an` annular re- .tainer intermediate the packing and valveoperating member for holding the packing c in place.

3. In a valve mechanism, the combination .with ay tubular valve casing, of a'. tubular concentrically arranged member extending hwithin the casing and connected thereto, a

shell valve interposed between the casing and member controlling they casing inlet, an annular packing between' the valve' and casing, and av similar packing between the valve and concentrically arranged member.

t. Inl a valve mechanism; the" combination with a tubular valve casing,`of a tubular concentrically arranged member extending within the casing' and connected thereto', a shell valve interposed between thev casing sov n and member controlling the casing inlet, and
